Have you ever seen how an impactor works in a factory?

No, I haven't, but I've heard they are really powerful machines.

Yeah, they can really shape materials by using force.

That sounds pretty impressive! I'd love to see one in action.

Root Explanation

Impactor is formed from "im-" (meaning into) and "pact" (from Latin "pactum", meaning to fasten or fix). The word refers to something that strikes or has a significant effect, as it 'fixes' or 'imprints' itself into a surface or situation.

Memory Tip

Think of something that strikes 'into' ('im-') and 'fixes' itself ('pact') — that's why an impactor is something that makes a significant mark or effect.
